Question

Corpus haemorrhagic is a/an
A. Other name for corpus luteum
B. Other name for corpus Albicans
C. Blood clot in ovarian follicle before ovulation
D. Blood clot in the ovarian follicle after ovulation

Answer 1

Hint: Corpus haemorrhage is a temporary structure formed in the ovary. Once formed, they will quickly get converted into corpus luteum. The term refers to a visible clot of blood.

Complete answer:
Option A: Corpus luteum is a cell mass formed inside the ovary. They are temporary structures and are responsible for the synthesis of the progesterone hormone during the initial stages of pregnancy. The secretions of the corpus luteum prepare the body to conceive. And these hormones induce the formation of a lining inside the uterus. And the secretion stops around 14 days after ovulation.
Therefore, this is the incorrect option.

Option B: Once the ovulation happens, the corpus luteum prepares the body to conceive the zygote. But in the absence of fertilization of oocyte within a certain period of the cycle, corpus luteum degenerates into a scar within the ovary. This structure is known as corpus albicans. Therefore, this is the incorrect option.

Option C: There will be no blood clot in the ovary before ovulation. The blood clot in the ovary forms after the release of the ovum and the collapse of follicles. Therefore, this is the incorrect option.

Option D: Immediately after ovulation, the ovarian follicle cells form a temporary structure known as corpus hemorrhagicum. They are collapsed follicles filled with blood that clots easily. Corpus haemorrhagicum then develops into corpus luteum. Therefore this is the correct answer.

Hence, the correct answer is option (D)

Note: The follicle cells which release ovum in the previous menstrual cycle give rise to corpus luteum and corpus haemorrhagicum. And they form at every menstrual cycle. If the ovum is fertilized, the corpus luteum remains inside the ovary.
